Aerospace & Defense startup Grid Aero raises $20M Series A to scale long-range autonomous airlift

Grid Aero, an aerospace startup building low-cost, autonomous aircraft for long-range operations, today announced it has raised a $20 million Series A co-led by Bison Ventures and Geodesic Capital, with participation from Stony Lonesome Group and Alumni Ventures, alongside returning investors Ubiquity Ventures, Calibrate Ventures, and Commonweal Ventures.

Grid Aero designs rugged autonomous aircraft capable of carrying thousands of pounds over thousands of miles. By pairing ultra-simple, low-cost airframes with cutting-edge autonomous systems, Grid Aero delivers uncrewed aircraft that can operate reliably from austere or degraded locations where infrastructure is limited, airspace is contested, and traditional logistics planning assumptions break down. Unlike complex legacy platforms, Grid Aero’s aircraft can also be deployed forward and operated at fleet scale, offering persistent logistics, sensing, and operational capabilities at a fraction of the cost.

“We’re focused on solving major problems for the warfighter, starting with contested logistics,” said Arthur Dubois, CEO of Grid Aero. “Those same challenges of range, resilience, and operating in constrained environments also define many commercial, humanitarian, and remote operations. This funding allows us to rapidly field autonomous aircraft to deliver scalable capability into real-world operations to meet growing demand across missions.”

The new funding will advance Grid Aero’s Lifter Lite aircraft from testing into operational deployments, supporting major exercises and early customer use cases while accelerating the transition from a validated prototype to a fielded platform. Coming just over a year after the company’s founding, the round reflects both the magnitude and urgency of the problem and investor confidence in the team’s speed of execution.

Grid Aero's focus has proven prescient. Last November, the Department of Defense released six critical technology areas, three of which — Contested Logistics, Applied AI, and Scalable Autonomous Systems — closely align with what Grid Aero has been building since day one.

Ben Hemani, Founding Partner at Bison Ventures, pointed to Grid Aero's execution speed: "What Grid Aero has accomplished in less than 18 months is rare. Not only have they already built their flagship aircraft, but they are also building a logistics capability that operates where traditional systems can’t. We’re excited to fund the next phase of their growth, as they move from rapid development to real-world scale.”

While Grid Aero is already proving itself in defense, the company is already attracting interest beyond it. Recent partnerships with Everts Air and Aviation Without Borders highlight how the same autonomous platform can support remote communities, humanitarian missions, and persistent aerial operations where conventional solutions fall short. Across sectors, the challenge is the same: delivering reliable capability where access is limited and failure is not an option.
